Just back from Rio De Janiero, Brazil, where I did plenty of filming with Professor Poliakoff for the Periodic Table of Videos.
It might be a short while until the videos are edited, but here are some snapshots to give a flavour of the trip. If you look closely, one of the world's great landmarks is dwarfed by Professor Poliakoff's hair.
Here I am, a bit closer to Cristo Redentor.
The famous statue (and it's miniature cousins) are carved from soapstone. We'll be talking about this in an upcoming video.
A periodic table display at a Rio museum was an important part of our visit - stay tuned for more details.
Professor Rodrigo Souza was our host in Rio - he showed us all the best restaurants!
We also finally go to met Professor Luis Brudna, who does all our Portuguese captions.
Brazil's national cocktail is the Caipirinha. I agreed to drink a few in the name of science!
I joined Professor Poliakoff only for the Rio leg of his trip to Brazil... But fans have been emailing me pics from Sao Paulo and Florianópolis.
Dr Pete Licence just texted me this very moody photo of our "cult hero technician" Neil Barnes.
Neil's more formally attired because he was helping set-up experiments for a professor's inaugural lecture - always a special occasion in a chemistry department.
I don't know if Pete did it on purpose, but the fire extinguisher is a great touch in this photo.
For those unfamiliar with Neil's work, I'd suggest the two videos below...
"Ah hah hah hah! They called me mad at the university...and they were right!"
The Crazy Scientist really loves mad science. He's got all the right equipment: a spooky old laboratory, shelves of beakers and tubes full of bubbling liquids, and even one of those antenna things with the little bolts of lightning that go up and down. He's still looking for just the right creepy assistant, but he's sure that one will answer his ad soon.
Not a typical day today... I was at Nottingham Crown Court.
It was for the sentencing of a woman who pleaded guilty to dangerous driving after crashing into a cyclist.
The victim was Donal McNally - himself a crash expert and someone I regularly feature in films on Test Tube.
Donal was cycling home in the evening of May 21 last year when he was struck down.
The driver left the scene and Donal was later found by passing motorists.
He was on bad shape and they initially thought he was "a large dog" on the road, the court heard today.
Donal had broken his neck in three places and suffered a burst fracture in his lower back.
The experts - including Donal himself - said he was very lucky to survive.
And what a twist of fate that a leading expert on crashes - and spinal injures - should find himself in such a predicament.
I filmed an interview with Donal a few weeks ago, but we couldn't upload it until the legal proceedings were finished.
Today the driver, a 28-year-old woman, was sentenced by a judge.
She was disqualified from driving for 18 months and ordered to perform 150 hours of unpaid work for the benefit of the community.
There were no charges relating to leaving the crash scene. An expert psychologist reported that she had a "genuine memory loss" of the incident and didn't know she had struck a cyclist.
The judge said he accepted this report.
As for Donal... well, the incident has strengthened his resolve to campaign about the importance of bicycle helmets.
He insists the helmet he was wearing (and which split in two places) is what saved his life.
In addition to the video above, we plan to post another video soon about the modeling his injuries and discussing safety in general.
